Application filed July 10, 1924. Serial No. 726,257.

To all/whom it may concern:

Be it known that I, Hl'LDING A.. SJODA'HL. a' citizen of the United States or America. and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have in vented new and useful Improvements in a Shingle, of which the following is a specification.

An object of my invention is to provide a shingle that may be utilized in providing a new and novel design for a roof or wall covering.

Another object of my invention is to provide a shingle where-with a large roof coverage may be attained with a relatively small number of shingles.

Another object of my invention is to provide a shingle wherewith adequate protection of the roof may be attained, notwithstanding the configuration of the roof and the relatively small number of shingles necessary for covering a given area of roof.

-These and other objects are attained by the me ns'described herein and. disclosed in the accompanying drawings, in which:

Fig. 1 is a view of a shingle embodying my invention.

Fig. 2 is a view showing a plurality of shingles disposed upon one-another.

Fig. 3 is a view of a sheet of material from which a plurality of shingles embodying-my invention are formed. v

The shingle disclosed herein may be made of any suitable material. for example impregnated felt, or the like overwhich is super-posed a layer oilcrushed slate or the like, as is commonly used for providing shingles 'ofithis uature. The shingle of my I invention has formed along its lower edge a 'iplurality ofdependingfiaps 10. .The lower edges f the flaps are developed into a point 11. The lower edges 12 and 13 of each flap 1O diverge 'from one another at an angle ofapproximately 140 degrees. The" lateral edges 14 and 15 of the flaps extend insubstantial parallelism with one another and are substantially perpendicular to the upper or inner edge 16 of the shingle. The shingle body 17 is recessed by providing converging downwardly disposed outer edges 18 and 19 for forming a recess or notch into the said i body portion 17 complementary to the point ed lower edge of the flaps 10. In other words, the adjacent flaps and recesses formed therebetween are substantially similar size and shape, the recess being reversed in position to the flaps.

When the shingles are laid, the point of one flap is disposed atthe unction point of the lower edges 18 and 19 of the shinglenext below. In this way a continuous zig-zag line is formed along the edges of the flaps in succeeding rows, said zig-zag lines extend- I ing diagonally across continuous shingles.

It will be observed that the edges 13 and- 18 extend in substantial parallelism and that edges 12 and 19 extend in substantial parallelism.

What I claim is; 1. A shingle of the class described having flaps formed along its exposed edge, the

flaps having their lower edges converging upon a point disposed substantially, at the center of the flaps and terminating upon the lateral edges of the flaps, said lateral edges extending in parallelism with one another and substantially perpendicular to the width of the shingle, said parallel lateral edges terminating upon edges of the body portion of the shingle extending in substantial parallelism with the lower edges of the flaps.

2. A shingle of the class "described pro-.-

vided along its lower edge with.alternate flaps and recesses, the flaps and recesses being identical in form and being reversed end for end, the flaps and recesses being bounded by a plurality of pairs of parallel lines, all of which are disposed at an angle to the width of the shingle.

3. A shingle of the class described comprising alternate flaps and recesses. the flaps and recesses being of substantially identical form and reversed end for end, the flaps comprising pointed lower ends having their lower edges diverging at an angle of substantially 140 degrees, having lateral edges extending from' said lower diverging flaps and extending in substantial parallelism with one another and having upper diverging lateral edges extending in substantial parallelism with the first mentioned diverging edges of the flaps.

4. A shingle of the class described comprising alternate flaps and recesses, the flaps and recesses being of substantially identical form and reversed end for end, the flaps comprising pointedlower ends having their lower edges diverging at an angle of substantially 140 degrees. having lateral edges extending from said lower diverging flaps and extending in substantial parallelism with one another and having upper diverging lateral edges extending in substantial parallelism with the first mentioned diverging edges of the flaps, the last mentioned diverging edges of adjacent flaps converging upon one another.-

5. A shingle of the class described comprising an integral body portion and flap, the flap being bounded by three pairs of parallel edges, one edge of the first pair of parallel edges connectin the ends of the a second pair of parallel e ges and the second edge of the first pair of parallel edges connecting the ends of the third pair of parallel edges, the second and third pairs of parallel 15 edges in combination extending the full Width of the shingle, and all three pairs of parallel edges extending at an angle to the Width of the shingle.

In'testimony whereof, I have hereunto subscribed my name this 5th day of July, 1924.
